I've got a Whirlpool WED9550WW1 (duet stackable dryer) that keeps blowing the high temp thermal fuse. The heating element is in good shape, not grounding out against the casing. Thermistor and other thermal fuse show continuity, along with the high temp thermostat. I checked the blower wheel and it seems to be operating properly. Oh, and yes, the air pathway is completely clear. Very short run to an outside wall.

Any ideas on what else it could be? I hate to mess with replacing the board until I'm 100% certain that's what it is.

I’m sure that there are some appliances guys on the board..in the meantime., I’ve made pretty extensive use of the forums at partsdr.com . Yes, they are selling you the parts...but their pice is the same or less than the local appliance parts store sells them for even when shipping is included. And they are super at diagnosing your problem as most responses are from employees of the site who seem to k ow what they are talking about. Pasted below is a link to the one of the threads dealing with your issue.

I’m only guessing that a thermostat is bad and the ythermal fuse is doing its job protecting you. Is there a thermostat in the beast?

Yes there's one connected to the heating element. It shows continuity so I'm assuming it's still working, but I ordered a new one just in case. From the other forum post it looks like if that doesn't do the trick, it's probably the main circuit board. Just don't want to drop $200 if I don't have to.
